Looking at kernel-features.h, it seems that a huge number of syscalls
were enabled first in 2.4.1.

I don't have any problem at all with increasing arch_minimum_kernel,
but I imagine some people do still use 2.4.x, so maybe we should just
modify arch_minimum_kernel to be 2.4.1? I can't think of _any_ reason
why someone would want to use plain 2.4.0.
